	* attribs.c (register_attribute): Added assert to check that all
	attribute specs are registered with a name that is not empty and
	does not start with '_'.
	(decl_attributes): Avoid the lookup of the "naked" attribute spec
	if the function has no attributes.
	* tree.c (is_attribute_with_length_p): Removed.
	(is_attribute_p): Removed.
	(private_is_attribute_p): New.
	(private_lookup_attribute): New.
	(lookup_attribute): Removed.
	(lookup_ident_attribute): New.
	(remove_attribute): Require the first argument to be in the form
	'text', not '__text__'.  Updated asserts.
	(merge_attributes): Use lookup_ident_attributes instead of
	lookup_attribute.
	(merge_dllimport_decl_attributes): Use remove_attribute.
	(attribute_list_contained): Likewise.
	(attribute_list_equal): Immediately return 1 if the arguments are
	identical pointers.
	* tree.h (is_attribute_p): Made inline.  Return a 'bool', not an
	'int'.  Require the first argument to be in the form 'text', not
	'__text__'.  Require the second argument to be an identifier.
	(lookup_attribute): Made inline.  Require the first argument to be
	in the form 'text', not '__text__'.
